Avant-Garde Polymer and Nano-Graphite-Derived Nanocomposites—Versatility and Implications
C, 2023 Graphite (stacked graphene layers) has been modified in several ways to enhance its potential properties/utilities. One approach is to convert graphite into a unique ‘nano-graphite’ form.

Influence of the carbon atom numbers and the structure of collectors on the coal fines flotation
Cogent Engineering, 2017 This paper highlighted measuring the contact angle, the wetting heat and the IR spectrum before and after interactions between eight alkanes and coals to investigate the influence of the alkane structure and the number of carbon atoms on the coal surface

Ion-beam-assisted characterization of quinoline-insoluble particles in nuclear graphite [PDF]
NUCL SCI TECH 31 (2020) 98, 2021 The irradiation behavior of graphite is essential for its applications in nuclear industry. However, the differences between graphite's behaviors are not well understood because of the very limited knowledge of microstructural differences between graphites.

Atomistic Evidence of Nucleation Mechanism for the Direct Graphite-to-Diamond Transformation [PDF]
arXiv, 2021 The direct graphite-to-diamond transformation mechanism has been a subject of intense study and remains debated concerning the initial stages of the conversion, the intermediate phases, and their transformation pathways. Here, we successfully recover samples at early conversion stage by tuning high-pressure/high-temperature conditions and reveal direct

Ultraviolet-visible spectroscopy of graphene oxides
AIP Advances, 2012 Dispersions of few-layer (1-3 layers), multi-layer (4-10 layers) and thick-layer (>10 layers) graphene oxide (GO) were prepared by a modified Hummers method with different mass ratios of KMnO4 to graphite.

Enhancement of the ferromagnetic order of graphite after sulphuric acid treatment [PDF]
APPLIED PHYSICS LETTERS 98, 192511 (2011), 2011 We have studied the changes in the ferromagnetic behavior of graphite powder and graphite flakes after treatment with diluted sulphuric acid. We show that this kind of acid treatment enhances substantially the ferromagnetic magnetization of virgin graphite micrometer size powder as well as in graphite flakes.

Tribology of Graphite-Filled Polystyrene
Lubricants, 2016 Self-lubricating polymer compounds are currently used for a wide range of applications such as bearings, gears, and water meters. Under severe conditions such as high pressure, high velocity, and/or high temperatures, the material fails (PV limit).
